Resolving the Poor Image Quality problems

All Troubleshooting procedures assume that only factory-authorized supplies are in use in the Printer.

Step Procedure

1Review the following information.

•Symptom: Photos on the cards look pixilated or grainy, as shown below.

•Printer Error State: None

•LCD Error Display: None

•Driver Monitor Error Display: None

2Use high-resolution, 24-bit color images to always capture an image:

•at a 24-bit color setting

•at 300 dpi

•at the same size that it will be printed on the card, as captured either with a scanner or with a digital camera

If a small or low-resolution image is stretched or blown up, a pixilated or grainy effect will occur when printing, as shown below (rightside).
